Alright so this all happened yesterday, i was just watching my regular youtube until a bunch of screamers just popped up and a messaage box with a hacker, without thinking i restarted my computer, and  when i booted it up it popped with with a cmd saying running asfx in my appdata local file. This never happened to me before. I ran the folder on malwarebytes, and it detected nothing, i suspect it was that file that did it, help? Also the file inside of it was an exe. nfjfk.exe Im windows 10. Im scared, please i dont know what to do so i came on this forum for help. 

 

EDIT: forgot to mention, i tried deleting the file but it didnt let me, it told me that the file was already running or something like that. And the file was created 12/1 and was used yesterday and im using premium version of Malwarebytes

G'day and Welcome,

 

 

I need to advise you that I am only a Standard Member, like you. I am not a Trained Malware Removal Expert. As such I'm limited in what tools I can use and the advice I can give. If you have any concerns about the advice or information I give, please contact a Moderator before actioning it.

 

 

I'm happy to try and help you sort out this issue if you wish?

 

 

If so, please continue....

 

 

 

Do Not Enclose Reports In Quotes or Delete or Insert Any Characters - No Redaction!

Please Post All Reports in Plain Text. Ensure You Include All Report Headers.

Please Press the Return Key 3 Times Between Reports.

Don't Attach them either.....Pleeeez!

 

 

Please make sure you have Backed Up your Files and Save any Work you have Open before proceeding!

You can find Free Back Up Software in the Bleeping Computer "Downloads" Section.

It's unlikely that anything I ask you to do will wipe your data, but better to be safe than sorry.

 

 

Some Tools May Close Down Any Open Windows or Programs, Please Be Aware of This!

 

 

 

Remember that there is no such thing as a "Stupid Question." If you encounter ANY problems or difficulties along the way, STOP and Message Me!!

 

 

 

**Read All Notes Under Individual Instructions BEFORE Running the Tools.**

 

You might find it useful to print these instructions for reference.

 

 

 

 

My suggestions:

 

 

(1)

 

 

 

Download a copy of a program called RKill (Courtesy of Grinler at Bleeping Computer) which is available at the links below:

(This program attempts to stop any running malware processes so other tools may function efficiently, plus a few other things.)

 

Save it to your Desktop so you can easily locate it.

 

(If one won't run, download the other. Malware sometimes recognises RKill.exe and tries to interfere with it.)

 

 

RKill.exe                              <<== Try this first.

 

RKill as iExplore.exe         <<== Try this one if option one doesn't work.

 

  • Right Click RKill and Select "Run As Administrator."
  • Soon after a Black Box will appear while RKill Runs. (This is normal. RKill may appear to hang. It's just working.)
  • When the RKill has finished it will Open a Report in Notepad.
  • RKill will also save a copy of its log to your Desktop called "RKill.log"
  • After RKill has run successfully Don't Restart your computer until the other tool(s) have run.
  • Please Copy and Paste the contents of the Report into your Next Reply.
  • If the RKill will not run in Normal Windows Mode, Restart in Safe Mode and Repeat the above Steps.

 

NOTES:

 

Please Ignore any warnings from about RKill containing Viruses or Trojans etc. If necessary, shut down or temporarily disable your Antivirus while RKill runs. Don't forget to Re-enable your Anti-Virus once RKill completes, unless I ask otherwise.

 

If RKill still won't run, please Post back here and advise me.(After trying both versions and Safe Mode.) Please note any Error messages or other useful information and Include it in your Reply.

 

 

(2)

 

 

Please download Security Check Tool (by screen317) from HERE & save it to your Desktop.

 

 

  • Right Click SecurityCheck and Select "Run As Administrator."
  • Follow the Prompts in the Black Box which opens on your screen.
  • When the program is complete a Notepad Document called Checkup.txt should open Automatically in Notepad.
  • Please Copy & Paste the Contents of Checkup.txt into your Next Reply.

 

Please Note the Following:

 

If you receive an "UNSUPPORTED OPERATING SYSTEM! ABORTED!," please Restart Windows and Security Check should Run Fine.

Should a problem persist, please Post Back Here and include any Error Messages & Other Useful Information.

 

Security Check may require you to permit "Dig.exe" to access the internet. Please allow access through your Firewall if necessary.

It is not uncommon for Security Check to generate "false positives" from  some Anti-Virus/Anti-Malware Programs. Please Ignore These if They Occur.

 

 

(3)

 

 

Download Farbar Service Scanner onto your Desktop (FSS:)  HERE

 

 

Please Ensure the following Options are Selected:

 

 

  • RpcSs and PlugPlay <= (May be greyed out.)
  • Internet Services
  • Windows Firewall
  • System Restore
  • Security Center/Action Center
  • Windows Update
  • Windows Defender
  • Other Services

(Please Don't Click the "Search Files" or "Export Service Buttons")

  • Click the Scan button to start scanning.
  • (FSS may take a short while to complete.)
  • When the Scan is Complete, a Report should Pop-Up in Notepad.
  • Please Copy and Paste the Contents into your Next Reply.

 

*(The Tool will create a log file called FSS.txt in the Folder the Tool is Run from.

That log will be saved. If there are any problems with the Pop-Up one, Copy from FSS.txt.)

 

 

(4)

 

 

Download MiniToolBox(By FARBAR) to your Desktop:  HERE

 

 

Right Click the Blue\Black MiniToolBox Icon and Select "Run as Administrator."

(The Tool will show Version: 17-06-2016 in the title bar.)

 

 

Select the following Check-boxes:

 

 

  • Flush DNS
  • Report IE Proxy Settings
  • Reset IE Proxy Settings
  • Report FF Proxy Settings (Make sure Firefox is closed first please.)
  • Reset FF Proxy Settings
  • List content of Hosts
  • List IP configuration
  • List Winsock Entries
  • List last 10 Event Viewer log
  • List Installed Programs
  • List Devices (DO NOT change any settings for this - Only "Problems" should be set by Default.)
  • List Users, Partitions and Memory size
  • List Minidump Files
  • List Restore Points

 

Click the "Go" Button.

 

  • Report should Pop-Up on your Screen in Notepad after a short wait.
  • Please Copy an Paste the Report Contents into your Next Reply.

(If you accidentally "kill" the Notepad Report, all is not lost, it should be saved on your Desktop as MTB.txt)

 

 

(5)

 

 

Download AdwCleaner(from Xplode.)   

 

From here: AdwCleaner.exe

 

 

Save to your Desktop so you can easily locate it.

 

  • Before Starting Ensure You've Saved Anything You Have Open that you Wish to Keep!!
  • Right Click AdwCleaner.exe & Select "Run As Administrator"
  • Please Click on the Tools Menu. There should be 2 Tabs: Options & Advanced.
  • In Options under DeleteSelect Tracing Keys(Usually pre-selected,) and, under RESET select all Options on the Right Hand Side.
  • Do Not select any other Options with Square Boxes.
  • There should be Options for Mode and Debug. You can leave these at their Defaults. Press OK.
  • Next, you should see Two main Buttons, Scan and Logfiles. Please Press Scan.
  • AdwCleaner will Start to Update the Database if required. This may take a little while.
  • The Progress Bar will gradually move to the right as the scan progresses. It can take a while.
  • Next you should receive a Popup Notification advising of the Scan Result.
  • Select any Items AdwCleaner may have found for DeletionorDeselect anything you may wish to keep.
  • Under the Popup there will be a Log. Please Copy and Paste the Contents into your next Reply.
  • NextClick Clean. This will require you to reboot the machine. Please do so.
  • Once the computer has rebooted, a second Log should appear. Please Paste into your Reply as well.

 

  • If you need to access Logs again, Open the Tool and Click the LogFiles Button. They are stored there.

 

The Logs can be a tad confusing at first. They all contain a number such as [S0] which is Log One. They are also accompanied by a date to the left side column. The lower the number in the square brackets, the earlier the Log. For example, I may have Logs; AdwCleaner[S0].txt (Earliest) to AdwCleaner[S27].txt (Most Recent.) Double Click a Log to Open it.

Next, as you have Malwarebytes installed on your Machine, please do the following:
 
Re-run the steps for RKill (Step 1. All Points.)
This is due to the Reboot Required after Running AdwCleaner.
 
  • Start the Malwarebytes Application.
  • Open the Malwarebytes Dashboard.
  • Ensure that Malwarebytes is Updated to the Most Recent Definitions and Version.(Version Update requires license or Trial.)
 
 
Click Settings, then Application:
 
Enable the Following Options If Not Enabled:
(If you do not have a license or trial activated some options will not be able to be set.)
 
  • Automatically download and install application updates
  • Notify me when full version updates are available
  • Show Malwarebytes notifications in the Windows System Tray
  • Show Notifications when Real Time Protection settings are turned off
  • Set Manual Scans have high priority
  • Configure Proxy Server if you use one. (If you don't know what this means you likely don't. If in doubt, CHECK!)
 
 
Now switch to the Protection Tab and where possible Enable:
(The same license note as above applies here too.)
  • Web Protection
  • Exploit Protection
  • Malware Protection
  • Ransomware Protection
  • Scan for Rootkits.
  • Scan within Archives.
  • Use Signature-Less anomaly detection for increased protection
  • Always detect PUPs
  • Always detect PUMs
  • Automatically check for updates (Select Check every 15 Mins.)
  • Notify if time since last update exceeds 24 hours
  • Start Malwarebytes at Windows Startup
  • Enable Self Protection Module
  • Enable Self Protection Early Start
  • Automatically Quarantine detected Malware
 
I suggest, when in this situation, using Threat Scan. Select Scans Tab. Select all Drives(C: D: etc.,) and ensure scanning for Rootkits is enabled. (The Rootkit option MAY not be available to you if you haven't activated Trial, or, don't have a license. I don't recall.)
 
  • If you'd rather not Use Threat Scan, Return to Dashboard and Click Scan Now.
  • Once Scan is complete, please Ensure any Threats found are Selected and Removed.
  • Please obtain a copy of your Scan Report from the Reports section and Paste in to your Next Reply.
